The year is 1923.

Jay Sinclair - heir to the Sinclair diamond fortune - moves to Sauquill Island off the coast of Providence, searching for the peace and solitude he needs to complete his new novel. But Sauquill is a troubling place, very quiet and calm one moment, frightening the next.

Visitors keep disappearing. Loud screams can be heard at night. And it all centers around Jay's new neighbor, a notorious and wealthy Russian poetess who throws wild parties at her house.

Nothing is quite what it seems. A net is being spread. A spell is being cast ... but not by any human being. The Great Old Ones are at work here, bending our minds to their will. They are coming back to claim our world. And Jay finds out he has become a helpless and unwitting pawn in their deadly, brutal plans.

Another Old One is arriving from the stars. And once that monstrous deity is here, the world will fully know the mastery of Cthulhu.
